Calcite.—Dunedin. 
In rhombohedral erystals lining an amygdaloidal cavity. The terminal 
group of rhombohedral faces (arranged in groups of three) have a bright 
lustre ; but the faces of the prism or elongated rhombohedron have drusy 
and brown-coloured surfaces. 
Calcite.—Chalky Inlet. 
A cleavage rhombohedron; opaque white, but almost iransparent in 
parts. i 
Calcite. —Moeraki. 
From a septarian; of a yellow colour; the under surface is studded 
with dark brown-coloured spots, which are apparently imperfectly-developed 
rhombohedral crystals. These spots are rich in iron and manganese. 
Before the blow-pipe the yellow colour is changed to. black; due to the 
presence of iron. One side of the specimen is irregular, from the presence 
of bold, but imperfectly-defined scalenohedral erystals. 
Calcite—Sunnyside, Dunedin. 
Smoky, translucent crystals of calcite, made up of the vidika 
combined with the scalenohedron. Associated with them are radiate groups 
of acicular natrolite crystals. 
Calcite.—Dunedin. 
The crystals are small, fairly well-developed acute rhombohedra, 
arranged together in a most beautiful little group ; the crystals are of a 
pleasing brown colour, with drusy surfaces. The calcite crystals are seated 
upon a thin coating of natrolite, which lines the amygdaloidal cavity. On 
the brown rosette of calcite is seated, in turn, a pretty little group of clear 
transparent crystals of some zeolite, apparently skolezite. 
Calcite.—Dunedin. 
In pale yellow transparent rhombohedral crystals; lining a cavity. 
P. Calcite, —Dunedin. 
Similar to the above. 
Calcite.—Dunedin. 
In small white rhombohedral crystals, seated on a pale brown-coloured 
calcite, lining an amygdaloidal cavity. 
Calcite.—Dunedin. 
Group of fairly well-developed rhombohedral crystals; pale greenish 
tint, translucent. 
Calcite .— Bunnyside, Dunedin. 
Small brown translucent crystals, consisting of the scalenohedron and 
rhombohedron combined; associated with one of the zeolites. The zeolite 
fuses easily to a clear glass, without intumescence.
